在新课程背景下的小学数学教学中,数学练习仅仅关注基础知识和基本技能是不够的,还要通过改变传统的练习方式,设计利于学生进行观察、操作、探索的练习,关注数学思想方法和一些解决问题的策略,关注积累基本的数学活动经验。因此,教师应认真钻研教材,根据教材知识结构和儿童的认识规律,以及教学的需要,精心设计练习,科学、合理地进行安排。笔者在多年的教学实践中悟出这样一个道理“学生在练中学,教师在练中讲”学生听得进,效果好。
In elementary mathematics teaching under the background of new curriculum, it is not enough to focus on basic knowledge and basic skills in mathematics practice, but also to practice the practice of observation, operation and exploration by changing the traditional practice mode, Some strategies to solve the problem, focus on the accumulation of basic mathematical experience. Therefore, teachers should carefully study teaching materials, according to the textbook knowledge structure and children’s cognitive rules, as well as teaching needs, well-designed exercises, scientific and reasonable arrangements. The author in the years of teaching practice to realize such a truth “students are practicing secondary school, teachers speak in practice ” students listen to, the effect is good.
